Kontra_Kommando has released the first beta version of his Alien: Trilogy mod for GZDoom. This mod converts Doom, Doom II, and Final Doom into a full-fledged Aliens game, in which players must face Weyland-Yutani androids, predators, and xenomorphs in a celestial battle for survival.
For this Alien Trilogy mod for GZDoom, Kontra_Kommando has basically combined Aliens:The Ultimate Doom with Alien Trilogy graphics. Moreover, Kontra_Kommando has created new attack rotations frames, blood and gore sprites, using the original Alien Trilogy graphics.
In short, this mod takes the aesthetics of Alien Trilogy, and combines it with the action and game play of Aliens the Ultimate Doom.
